Engineering practice of method of controlling lime content in lime-flyash soil roadbed construction

In the construction of highway, the quality of the filling material of roadbed is very important to the life of road transportation. Lime, flyash, and soil are mixed in the fixed proportion as the material for the roadbed, and it has high strength and good stability. But lime content in the mixture is the key factor to affect the strength and stability of roadbed. Therefore, how to control lime content reasonably and effectively in the mixture is a key link in the construction. Some methods of controlling the content of lime in limeflyash soil roadbed construction are discussed,combining engineering characteristics and actual circumstance, and which have some reference meaning for the roadbed construction.
